python2: Use system libffi on Aarch64

Browse source 
libffi needs a patch to actually work on aarch64 (or the cffi Python package
fails its testsuite). Of course the bundled version of libffi has the
same bug, so don't use the buggy version on aarch64.

Python3 already uses the system libffi on all platforms. I don't know
why Python2 doesn't.
